I have the following Kilgallons for 1856 in Kilmoremoy Parish:
January 13 - Anthony for Denis and Bridget Kilgallon, Bunree; sp. Thomas and Anne Naughton
January 17 - Ellen for John Kilgallon and Anne Murphy, Slievvenagark;sp. Nick and Mary Gilmartin
September 19 - Michael for Anthony Kilgallon and Bridget Coolican, Bohernasup; sp. Mary Quinn

1857

1855
Feb. 18 - Joseph for Thomas Kilgallon and Mary Crean, Hill St.; sp. Michael McNulty and Ellen Crean
March 17 - Patrick for Matthew Kilgallon and Winifred Moyle, Mullans; sp. Thomas and Mary Durkin

November 6 - Cate for John Kilgallon and Anne Murphy; Ardnaree, sp. Thomas Crean and Bridget Murphy
December 12 - Bridget for Pat Kilgallon and Bridget Robinson, sp. James and Catherine Robinson
I can't find a Pat whose father was also Pat. If he were born in Kilmore, it was difficult to read some pages because the ink bled through or was so faded I couldn't read it. However, there were quite a few Kilgallons in the parish.
